Specification of Letters Patent.

Patented May 28, 1907.

Application filed June 25,1906. Serial No. 323,284.

To all whom t may concern:

Be it known that I, RUDOLPH DEIMEL, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sofa-Beds, of which the following is a specification.

The main obj ect of this invention is to sim plify, strengthen, and cheapen the construction of sofa-beds of the type in which the back and seat are hinged together and movlble to different positions on the supporting ase.

These objects are accomplished by the structure shown in the accompanying drawings, in which:

Figure 1 is a transverse vertical section of a sofa-bed constructed according to this invention, and showing the back and seat in the horizontal position on the base. Fig. 2 is a similar section showing the seat raised in a suitable position to interlock with the back at right angles thereto and illustrating the irst step in converting the device into a sofa or davenport. Fig. 3 is a similar section showing the seat and back in their normal positions when used as a sofa or davenport. Fig. 4 is an end view of the middle part of the device as illustrated in Fig. 1, with the end pieces or side arms ofthe davenport removed. Fig. 5 is a section on the line 55 of Fig. 2. Fig. 6 is a section on the line 6 6 of Fig. 2.

In the device shown, the box 1 serves as the supporting base or body and has its end pieces 2 cut out at 3 to form trackways for the carriage 4`5`7. Said carriage consists of end pieces or uprights 5 beveled at 9 and connected together by means of a crosspiece 7, thus constituting a carriage having a rigid frame which extends between the end pieces 2 of the base. The uprights 5 are cut away at 6 and each provided with two pairs of rollers 7 and 8 bearing upon and against the inside of the end pieces 2 of the box 1. The seat or bed-section 10 is beveled at 11 to meet the beveled surface 9 of the uprights 5 of the carriage as shown in Fig. 41. The seat 10 is secured to the uprights 5 by means of hinges 12. The back or bed-section 13 is pivoted at 14 to the carriage and to the seat 10. The seat 10 and back 13 are pivotally connected by means of the plates 15 and 16. Said plates are provided with interlocking devices 17, 18 and 19, which serve to lock the seat and back at right angles to each other, as shown in Figs. 2 and 3. The arms or end pieces 2O ofthe davenport are secured to the end pieces 2 of the supporting base by means of bolts 21 extending through the slots 22 and held therein, against shifting, by means of nuts 23. Each of the arms or side pieces 20 of the davenport has secured along its lower part a strip 24 which has the head of the bolt 21 iirmly seated therein. This Aarrangement avoids having the bolt-heads on the outside, and permits the side pieces 20 and the supporting base to be readily assembled without the necessity of accurate measuring and boring of bolt-holes; and provides for their adjustment along the slots 22, to the proper relative positions.

The operation of the device is as follows: Vhen the parts are adjusted in the form of a bed as shown in Fig. 1, and it is desired to convert the device into a davenport or sofa, the seat 10 will be raised to the position shown in Fig. 2 so as to cause the link 17 to engage the pin 25, and lock the seat and back at right angles to each other. The seat will now be pulled downwardly, at the same time raising the back 13 to the upright position.

The parts will then be pushed back with the i carriage to the position shown in Fig. 3.

To convert the parts into a bed, the seat will first be pulled out to the left of Fig. 3 until the carriage reaches the position shown in Figs. l and 2. The seat will then be tipped up to the position shown in Fig. 2 and pushed slightly forward of said position so as to release the link 17, and will then be lowered into the position shown in Fig. 1.

What I claim as my invention and desire to secure by Letters Patent is:

1. A sofa-bed comprising a supporting base having a pair of parallel end pieces, a carriage having a rigid frame extending between said end pieces, having rollers bearing A upon the upper surface of each of said end pieces, and a roller bearing upon the side of each of said end pieces, a pair of bed-sections pivoted to said frame, and means for locking said bed-sections on their pivotal connection, at an angle to each other.

2. A sofa-bed comprising a supporting base having a pair of parallel end pieces, al

carriage having a cross-piece extending between said end pieces and having rigidly se-` IOS cured to each end thereof an upright with a part extending above the adjacent end piece, carrying rollers bearing upon the upper surface of said end piece, and a roller bearing rio upon the side of said end piece, a pair of bedactions pivoted to said uprights, and means or lo cking said bed-sections, on their pivotal connection, at an angle to each other.

3. A sofa bed comprising a supporting base, a carriage running transversely of said base, said carriage having a rigid frame extending between the ends of said base and having a pair of uprights each consisting of a broad lower part tapering upwardly, said uprights being rigidly connected by a cross piece extending between their lower parts, a pair of bed-sections pivoted to each other and to said uprights, one of said bed-sections being cut away to fit said tapered uprights, and means for locking said bed-sections at an angle to each other.

4. A sofa-bed comprising a supporting base havin each of its end pieces provided with a trac i, a carriage having upright end pieces riding on said track and having depending parts extending downwardly adjacent to said end pieces and carrying rollers bearing against the inner sides of said end pieces, the upper faces of said uprights being beveled, a pair of bed-sections pivoted together and to said uprights and one ofthe same being beveled to fit the beveled surfaces of said uprights, and means for locking the said bed-sections at an angle to each other.

5. A sofa bed comprising a supporting base, a carriage running transversely of said base, said carriage having a rigid frame extending between the ends of said base and having a pair of uprights each consisting of a broad lower part tapering upwardly, said uprights being rigidly connected by a cross piece extending between their lower parts,

' and a pair of bed-sections pivoted to each other and to' said uprights, one of said bedsections being cut away to fit said tapered uprights.

6. A sofa-bed comprising a supporting base having each of its end pieces provided with a track, a carriage having upright end pieces riding on said track and having depending parts extending downwardly adj acent to said end pieces and carrying rollers bearing against the inner sides of said end pieces, the upper faces of said uprights being beveled, and a pair of bed-sections pivoted together and to said uprights and one of the same being beveled to fit the beveled surfaces of said uprights.

7. A sofa-bed comprising a supporting base in the form of a box having opposite end pieces recessed to form a track, a carriage having a rigid frame extending across between said end-pieces and riding on the track in each of said recesses, a pair of bed-sections pivoted to said carriage, and means for locking said bed-sections at an angle to each other.

8. A sofa-bed comprising a supporting base in the form of a box having opposite end pieces recessed to form a track, a carriage having a rigid frame extending across between said end-pieces and riding on the track in each of said recesses, and a pair of bed-sections pivoted to said carriage.
